with
We can use the with keyword, which will close the file for us after we’re finished:
with open("phonebook.csv", "a") as file:
writer = csv.writer(file)
writer.writerow((name, number))pass
Another place pass can be used is as a place-holder for a function or conditional body when you are working on new code, allowing you to keep thinking at a more abstract level. The pass is silently ignored:
def initlog(*args):
... pass # Remember to implement this!
